This invention has to do in a general way with the art of molding clay, and is more particularly related to machines for molding 4articles such as flower pots and the like, having as a primary object the production of a machine of the class described which is of simple form and construction and is entirely automatic in its operation.

It is a noteworthy feature of the machine contemplated by this invention, that. the only manu-al operation necessary in the molding of an article consists of placing a ball of clay in a mold, the remaining operati-ons of forcing a core into the mold and extracting l the formed article being automatically carried out by the machine. It is entirely p-ossible, of course, that the clay might be-apportioned and delivered to the machine automatically, but mechanism for carrying out this operation forms no part of the present invention.

The general construction of the machine contemplated by our invention comprises a rotary table which is equipped with means foi imparting intermittent rotation thereto, a vert-ical reciprocating core member, and an extracting member. The core member and the table rotating mechanism are `so timed and so correlated that the table is rotated only at such times as the core is positioned thereabove. In order that the table may be held in the position in which one of the molds therein is in exact alignment with the core, we provide the machine with a locking mechanism adapted'to engage the table when it roaches such a position, and for the purpose of releasing the table when the core has been elevated to a position at which the table can be rotated, we provide releasing means for disengaging the lock, such means in this form of our invention being operated by the same mechanism which imparts reciprocation to the core. The rotary table is provided with a plurality of molds, such molds being equipped with extracting means and arranged so that one of the molds is positioned above an extracting arm or lever when another of the molds is situated below the core.l 'i

It is necessary in the construction of a machine of this character, that all of the parts ,be correlated so that the operation takes place at the proper time. In order to effect this ref sult m the most satisfactory manner, we have constructed the machine so that allof the operative parts are controlled from a single source of power. i

It is sometimes necessary, in working upon Vclays of various textures, to act upon the clay molding of clay articles of the type referred n to above, it is important that the core member be rotated during its entrance into the mold. We have, therefore, produced a core operating mechanism which is constructed vso that the core receives reciprocating and rotating motion at the same time.

Figs. 6a, 6b, 6c, and 6d are diagrammatic views illustrating the operation of the table control ratchet.

More particularly describing` the invention as herein illustrated, reference numeral 11 indicates a frame consisting',- of a base member 12 and standards 18 and 14. The standards 13 and 14 support what we will term a top plate 15. The plate 15 carries bearings 16 which in turn support a main drive shaft 17. The outer end of the drive shaft 17 carries a gea-r 18 which is in mesh with the pinion 19, the pinion 19 being adapted to receive rotation from a friction disk 20. The friction disk 2O is rotated by a friction wheel 21 which Yis adjustably mounted upon a vertical shaft 22 carried by bearings 28 and driven by a motor 25 which is supported by a suitable bracket 26 mounted on the side of the standard 14. A worm 27 is keyed to the drive shaft 17 and is in driving engagement with the worm wheel 28, which in turn is keyed to the crank shaft 29, the latter member being mounted between suitabl bearings 30.

Mounted upon the outer face of the standard 18 is what we will hereinafter refer to as a housing, indicated by reference numeral 35. The details in the construction of the housing 35 are best illustrated in 4, where it isr shown as consisting' of a housing section 86 which has bearing ,apertures 87 formed yon opposite sides thereof, such apertures being adapted for the reception of a short shaft 88 which carries a racking gear 89- and a pinion 40. A longitudinal bearing passage 41 is formed Vin the head of the housing 85 yand this passage is adapted to receive a reciprocating sleeve 42 which is provided 'f with a rack 43 adapted to be enO'aO-ed by the A F 's gear 89. The reciprocating sleeve 42 contains a rotating spindle 45, the upper end of such spindle extending through a bearing 46 vfbrmed on the end of the top plate 15 and the lower end of the spindle is provided with a core, indicated by, reference numeral 47.

Relative movement between the spindle and the sleeve 42 is prevented by a colla-r 48 which is keyed or otherwise rigidly attached to the spindle above the sleeve. The upper end portion of the spindle 45 is provided with flattened surfaces, as illustrated in Fig. 2, and extends through a correspondingly formed passage or aperture in a bevelled gear 50. The gea-r 50 is in mesh with a pinion 51 which is keyed to the outer end of the drive shaft 17.

The general construction described above, consisting of the sleeve 42, of a spindle 45, and core 47, will be hereinafter referred to as Va core member, and it will be understood from the foregoing description that this core member comprises an organization which is adapted to be vertically reciprocated and in which the core thereof is adapted to he rotated during such reciprocation by means of the spindle 45.

For the purpose of effecting the reciprocation of the core member, we provide the machine with a crank and lever mechanism, consisting of a segmental gear 52 provided with a rigid shaft 53 adapted to be received in a bearing member 54 which is mounted on the inner surface of the standard 13. The segmental gear 52 is equipped with a lever 55, the end portion of which is provided with a slot 56 which is adapted to adjustably receive a pin 57, which in turn is connected with the lower end portion of a sectional connecting member 58. rl`he upper end portion of the connecting member 58 is pivotally attached to a crank 59 through the medium of an offset connecting member 60. The crank 59 is keyed or otherwise rigidly attached to the crank shaft 29. i

The details in the construction of the connecting member 58 are best illustrated in Fig. 9, where this member is shown as comprising an internally threaded thimble 65 provided with an apertured ear 66, whereby the member 58 is attached to the lever 55 by the pin 57, and which receives the lower end portion of an externally threaded sleeve 67. The sleeve 67 has a shoulder 68 formed in its lower end, such shoulder being adapted to act as an abutment for a washer 69 which is mounted on the lower end of a pin 7 0 and is retained thereon by means of a nut 71. The pin 7 O is secured in the lower end portion of a rod 72 which slidably extends into the threaded sleeve 67. The upper end portion of the rod 72 is provided with a shoulder 78 which is formed below the `bearing member 7 4 through which the rod 72 is connected to the offset cennecting member 6() (Fig. 5) by means of pins 75. rlhe rod 72 is yieldably held against sliding movement within the sleeve 67 by means K From this member.

ing member 58 may be yieldably compressed,l

such vcompression being for the purpose of permitting a continued movement of the crank' 59 after the core 47 has reached the The pur` limit of its downward movement. pose of this construction will be best understood from the following description of the rotary table and the operation of the-core Suffice to say at this time that it is important for the most satisfactory opera- Y tion of a machine of this character thatthe core be held in the mold under pressure and rotatedtherein over a limited period after it reaches the bottom of its stroke. The compression of the connecting member 58, as mentioned above, permits this operation.V

Reference numeral indicatesa.- rotary table which is mountedupon the upper end of a vertical sha-ft 81, the latter member'having its lower end portion situated in a bearing 82 mounted on the base member 12 and its upper end portion in abearing 83 which is contained within ay vertical shaft housingA 84. The rotary table 80 contains a plurality7 of (3) molds which are generally indicatedA machine, similar variations being made in the core 47. Each of the molds is shown as havinga false bottom 88, such false bottom being provided with downwardly projecting stems 89, the stem extending through bearings which are supported by downwardly extending brackets 91. This construction permits the extracting of the article formed in the mold simply by pushing the stems and the false bottoms upwardly through the molds after the articles have been formed.

The movement of the stems 89 and the consequent extraction of the article from the mold is accomplished through the medium of an extracting lever generally indicated by reference numeral 95, and shown as being mounted upon a pivot shaft 96 which is supported by suitable bearing plates 97 formed upon the base member 12. The outer end portion of the extracting arm or lever is provided with a shoe 98 which is situated so as to engage the lower end portion of one of the extracting stems 89 when another of the molds is situated below the core 47.

necting rod 99 which has its lower end pivot# 0 ally attached to one end of the lever 95, as indicated at 100, and has its upper end portion pivotally attached to the offset'connecting member 60, as clearly illustrated in Fig.

The ex-` tracting arm or lever 95 is operated by acon- 1 described that when the' core 47 is i' being moved downwardly into themold situatedr below the same, the shoe 98on the outer end of thejextracting lever 95 'is beingraised, since Vboth the extracting lever controlrod 99 and the connecting rod 58 whichcontrols the core reciprocating mechanism, are operated by the same crank ony the crank shaft 29;

Theintermittent rotation of the shaft 81 and the consequent intermittent rotation of theftable 80 is effected through theV medium.

of a table rotating shaft105, such shaft being carried by bearings 106,106 and 107 in the standards 14 and -13 and the vertical shaft housingl 84, respectively. The movement. of theshaft is accomplished'by a ratcheting organization 'generally indicated y,by reference numeral 108. This organization is op-v erated by a connecting rod`109v, the upper end portionv of which is attached to a V,crank 110` which is also keyed to the crankshaft 29. The details in J the construction of Vthe ratchet organization 108 are best illustrated. in Fig. 6 and the operation of this organiza# tion is clearly illustrated in Figs. 6A to 6D, inclusive. The ratchet organization y108 con# sists of a ratchet wheel 115, which is keyed to' the shaft 105, anda secondary ratchet wheel `116 which is freely. rotatable upon the shaft 105. lThe rotation of the ratchet wheel 116 upon the shaft 105 is retarded by means of a plurality of spring pressed frictional pins indicated at 117. The` movement of the ratchet'wheel or the ratchetwheels, as the case may be, is effected through themedium' of a pawl member 120 which is pivotally attached to the lower end of the connecting rod 109, as indicated at 121. This pawl member is pivotally mounted between pawl plates 122 and 122upon a transverse pin 123 and a spring pressed stop pawl 124 is mounted upon a pin 125 connecting the ends of the plates oppositeto which the pawl member 120 is attached; The stop pawl 124 is adapted to pre- 10".

vent the shaft 105 and its associated parts, including the table 80, running ahead of.l the ratchet.

It will be noted from Fig. 7 that the pawl member 120 and the stop pawl'124 are made of substantially the same width as the ratchet wheel 115, which is rigidly attached to the shaft 105 and, as shown in Fig. 7, these pawl members are held away from the pawl plate 122 by means of spacing washers 126l and= ratchet wheel 1,15 is provided with four notches of equal depth and the ratchet wheel` 116 is provided with two notches having the same depth as the notch on the wheel 116 and with another pair of notches which are of a depth such that the inner surfaces of these notches-'clear the periphery ofthe. wheel 115. Itis through the use of this construction that we provide a mechanism whereby the machine It will alco be noted from Fig. 6 that the i `tion permits the table being held stationary while the core4 member. reciprocates'a plu-A rality of times. In the operation of this device when it is desired that the table be ad-Y vanced after each movement of the coreintol one of the molds, the pawls 120 and 124 are set in the manner indicated inFig. 7. 7l/ien set in this manner the pawl 120 will engage one of the notches 130 onthe ratchet "wheel 115 for each reciprocation ofthe rod 109. Thel arrangement of Vthe crank 110 with respect to the crank 59 is such that this engagement between the pawl 120 and the notch 130 will not take Yplace until the vcore 47 has been liftedl from the mold which issituated therebelow. It it is desired that each article in the mold be subjected to a double action of the core 47, the spacing washers 126 and 127 areremoved and placed on the oppositesides vof the respective pawls 120 and 124. When lar-V ranged in this manner, the parts occupying the position shown in Fig. 6, the continued upward movement of therod 109 will carry the ratchet wheel 115 upwardly through 90O so that the shallow notch'132 on the freely rotating ratchet wheel 116 will be brought to the position occupied bythe deep notches v130 and 131 in the wheels115 and 116. During the next reciprocation of the rod 109 the pawl 120 will engage the shallow notch 132 and through such engagement will be rotated clear of the ratchet wheel 115. In this manner the shaft 105 receives no movement from this reciprocation of the rod 109, and since the remainder of the machine continues to operate in the usual manner, the article in the mold is subjected to two actions of the core 47 before the table is next rotated. In view of the fact that the reciprocation of the core member 47 and the partial rotation of the table 80 must be effected during one complete rotation ot the crank shaftA 29, it is important that the ratchet organization 108 be constructed so that the ratchet wheel or the ratchet wheels receive movement over a yfraction (substantially 90o) of the4 complete movement of the crank shaft 29. This is the main reason for pivotally mounting the pawl 120 between the pawl plates 122 and 122', and the action of this mechanism 'is clearly illustrated in Figs. 6A to 6D, in

elusive. Fig. 6A. shows the position of the pawl 120 lat the bottom ofthe stroke. of connecting'rod109. It will be seen that the pawl has a substantial 'movement before it is brought into active engagement with the ratchet wheel 115.VV lVith the continued up-` ward movement of therod 109k in the direction of the arrow A, the pawl 120is brought into engagement with the notch 130 in 'the ratchet wheel, as illustrated in Fig. 6B.l The further upward movement of the rod 109 rotates the ratchet wheel around to theV position shown in Fig. 6C, such rotation being effective Vto rotate the vertical shaft 81 Y through the medium of differential gears 81',

a distance suiicient to carry the next mold beneath the core 47. The position shown in Fig. 6C Vis the positionoccupied by the members when the rod 109 has been moved to the completion of its up stroke. The initiationof the downward movement of the rod swings the pawl 120 into the position shown in Fig. g 6D and carries the pawl ,platesV 122 and 122 downwardly into the iirst position shown in Fig. 6A.

It was mentioned in the fore partV of the specification as one of the objects of this invention, to provide means for locking the table against rotation while a moldwas held beneath the core. Such locking means are indicated generally by reference numeral 135,

the locking means 135 consisting of a sliding.y pin or bar 136 which is contained within a suitable bearing member 137 shown as hav-V medium of a pin and slot mechanism, to the Y downwardly projecting arm 140 Vof a bell crank 141. This crank is pivotally supported by-a bearing member 141', which is mounted upon the standard 13. The movement of the bell crank 141 is eiiected through the. medium of a connecting rod 142 which has its upper end attached to the outer end of a lever 143 whichvis pivoted to the top plate 15, as indicated by reference numeral 144. The lever 143 is situated so as to be engaged by the outer end of the crank f59 in the manner illustrated in Fig. 5. The weight of the connecting rod 142 and its associated parts is sutlicient to normally maintain the bar or pin 136 toward an inwardly extending position, and it will be seen from Vthe construction so far described, and as is clearly illustrated in Fig. 10, that the movement of the crank 59 upwardly to a position after which the core 47 has been removed from the mold, is effective to raise the lever 143 and unlatch the table 80, so that the continued movement of the crank 29 and the Vconsequent engagement of the pawl 120 with the ratchet wheel 116, is effective to rotate the table 80 into the next position. It will also beapparent that after the crank 59 has advanced substantially O from the 'position` shown in Fig. 10, that the lever 143 will dropl back to its normal position, placing suiiicient weight upon the bell crank 141 to force the pin 136 into the notch 139 when the table has been moved to a point at which such notch is opposite the pin. Also, it should be noted `that the position of the crank 110 Vwith respect to thecrank 59 ,is such that the racking action of the table illustratedin Figs. 6B and 6C, is imitated just after the lever 59 reaches the position shown in Fig. 10.

It will be seen from this construction' that the mechanism for rotating and locking the table and the mechanism for reciprocating the mandrel are so tied togetheror correlated that vall ot the parts are arranged in the proper position with respect to each other at the proper time. In other words, the core 47 is always out of the mold when the table is to be rotated and a mold is always situated beneath the core when the core is being advanced downwardly toward the table.-

For the purpose of counterbalancing the core 47, we attach .a flexible member 147 to the upper end of the sleeve 42, as indicated at 148. This member extends over pulleys 149 and 150 which are supported by the standards 13 and 14, respectively, and has a weight 151 attached -to its lower end.

"Reference numeral 152 indicates a braking device provided for the purpose of holdinO the table against any rotative movement other lth an `that which is imparted to it by the racking mechanism. lThis braking device is shown as comprising a shoe 153 which .hasa

'boss 154 on its upper surface projecting into an aperture Jformed in the member 138. i `The shoe is held in pressure engagement with the edge of the table by a compression spring 155 which is retained in the aperture 'by a `plug 156.'

` In order that the downward travel of the core member and the consequent thickness-of the clay inthe mold may be controlled 'to any desired extent, we provide the core member with a stop which may be set to engage ythe upper surfaceof housing 35 when the core member has reached a predetermined f is not limited to the precise construction described (above, but includes within its scope whateverchanges -fairly come within the spirit `of the appended claims.
